4. HOW TO INSTALL THE OUTDOOR UNIT
4-1. Installing the Outdoor Unit
●
Use concrete or a similar material to make the
base, and ensure good drainage.
●
Ordinarily, ensure a base height of 5 cm or more.
GB
If a drain pipe is used, or for use in cold-weather
regions, ensure a height of 15 cm or more at the
feet on both sides of the unit.
(In this case, leave clearance below the unit for
the drain pipe, and to prevent freezing of
FR
drainage water in cold-weather regions.)
●
Refer to the Fig. 4-1 for the anchor bolt
dimensions.
●
Be sure to anchor the feet with anchor bolts
DE
(M10). In addition, use anchoring washers on the
top side. (Use large square 32 × 32 SUS washers
with JIS nominal diameter of 10.) (Field supply)
4-2. Drainage Work
IT
Follow the procedure below to ensure adequate
draining for the outdoor unit.
●
For the drain port dimensions, refer to the figure
at right.
●
Ensure a base height of 15 cm or more at the feet
PT
on both sides of the unit.
●
When using a drain pipe, install the drain socket
(optional part STK-DS25T for 4, 5, and 6 HP
units, STK-DS13U for 2 HP unit) onto the drain
port. Seal the other drain port with the rubber cap
GR
supplied with the drain socket.
●
For details, refer to the instruction manual of the
drain socket (optional part STK-DS25T for 4, 5,
and 6 HP units).

4-3. Routing the Tubing and Wiring
●
The tubing and wiring can be extended out in 4
directions: front, rear, right, and down.
●
The service valves are housed inside the unit.
To access them, remove the inspection panel.
(To remove the inspection panel, remove the 3
screws, then slide the panel downward and pull it
toward you.)
(1) If the routing direction is through the front, rear,
or right, use a nipper or similar tool to cut out the
knockout holes for the inter-unit control wiring
outlet, power wiring outlet, and tubing outlet from
the appropriate covers A and B.
(2) If the routing direction is down, use a nipper or
similar tool to cut out the lower flange from
cover A.
CAUTION
●
Route the tubing so that it does not contact the
compressor, panel, or other parts inside the unit.
Increased noise will result if the tubing contacts
these parts.
●
When routing the tubing, use a tube bender to
bend the tubes.
●
In cold-weather regions, in order to prevent
drainage water from freezing, do not install the
drain socket cap. Also take steps to prevent
water from accumulating around the unit.
